UNITED STATES WILLIAM H. GAIN, OF LOS ANGELES, CALIFORNIA.

GAS-RADIATOR.

Specification of Letters Patent.

Patented May 20, 1919.

Application filed April 1, 1918. Serial No. 226,090.

T0 all whom t may concern:

Be it known that I, WILLIAM H. GAIN, a citizen of the United States,residing at Los Angeles, in the county of Los Angeles and State ofCalifornia, have invented new and useful Improvements in Gras-Radiators,of which the following is a speciiication.

My object is to make an ,improved gas radiator and my invention consistsin the novel features herein. shown, described and claimed.

Figure 1 is a front elevation of a gas radiator embodying the principlesof my invention, the view being taken looking in the direction indicatedby the arrows 1 in Figs. 2, 3, 4 and 5, parts being broken away andshown in section.

Fig. 2 is a side elevation looking in the direction indicated by thearrows 2 in Figs. 1, 4 and 5.

Fig. 3 is a vertical cross-section on a plane parallel with Fig. 2 andon the lines 3 3 of Figs. 1 and 4.-.

Fig. 4: is a horizontal section on the lines 4.-4: of Figs. 1, 2 and 3.

Fig. 5 is a staggered horizon-tal section on the lines 5 5 ofFigs. 1, 2and 3.

Fig. 6 is a fragmentary vertical longitudinal section on the line 6 6 ofFig. 3'.

Broadly, my improved radiator comprises a supporting section 1, a burnersection 2 secured to the bottom of the supporting section 1,intermediate sections 3 extending upwardly from the supporting section,and a cap section 4t on top of the intermediate sections 3.

The supporting section 1 comprises a bottom 5 havinggaJ longitudinalburner opening 6, legs 7 extending downwardly from the four cornersofthe bottom, a front wall 8 extending upwardly from the bottom, a rearwall 9 extending upwardly'from the bottom, end walls 10 and 11connecting the front and rear walls and extending upwardly from thebottom, a top wall 12 connecting the upper edges of the walls 8, 9, 10and 11 and having a series of front flue openings 13, a series of rearflue openings 14:, and a baflie wall 16 extending downwardly from thetop and forwardly to the front, there being a by-pass opening 15 leadingdownwardly from the center of the bathe to near the bottom, thus forminga combustion chamber 17, said by-pass opening 15 communicating with thecombustion chamber above the bottom 5 and there being lighting openings18 through the wall 8. Y

The details of the intermediate sections 3 are as follows: In theradiator shown I have imitated a live-section steam radiator, therebeing five up-draft flues 19, the lower ends of the tlues resting uponthe top 12 around the openings 13, and vthere are four down-draft iues2O resting upon the top 12 around the openings 14, and a center outletflue 21 resting upon the top 12 above the by-pass opening 15. The frontand rear walls 8 and 9 have undulations 22 and 23 extending between theflues, there being bolt'ng flanges 24 and 25 across the tops oftheundulations. A stove pipe nipple 26 leads laterally from the outlet flue21. A vpipe 27 is mounted through adjacent walls of the flue 21 and thecenter oneof the dues 19, the discharge end of said pipe being centrallylocated in the stove pipe nipple 26, and a flaring elbow 28 extendsdownwardly from the end of the pipe 27 in the center flue 19, so thathotl air passing upwardly` from the combustion chamber 17 will becollected by the open end of the elbow 28 and discharged through thepipe 27 to the stove pipe nipple 26 to start the draft, said pipe 27 andelbow 28 thereby serving as an injector.

The details of the cap section 4 are as follows: A rectangularhorizontal plate 29 has a front row of iue openings 30 corresponding tothe openings 13, a center rear web 31 closing the upper end of the flue21, and rear return flue openings 32 corresponding to the openings 14,there being beads 33 extending downwardly from all the openings 30, 31and 32 and beads 34 extending upwardly around all the openings 13,14C-'and 15, and the ues 19, 20 and 21 itbetween the cap and thesupporting section withinthebeads. Return bends 35 extendupwardly fromthe plate 29 crosswise of the plate so as to connect the front flues 19`with the rear flues 20, there being openings 36 connecting the returnbends together sidewise, so that the center bend which strikes the web31 may discharge laterally to the rear flues 20. Flanges 37 and 38 arethus left between the ends of the return bends, and rods 39 and 40connect the flanges 24 and 25 to the flanges 37 and 38 so as to hold thecap section 4 on top of the intermediate sections 3 and the intermediatesections 3 upon the supporting section 1.

The details of the burner section 2 are as follows; A rectangular plate41A fits upl wardly against the bottom 5 to cover the opening 6 and issecured in place by bolts 42. Burner heads 43 are screwed downwardlythrough the plate 41 in a row at the transverse center of the radiatorand extending from end to end, there being preferably eight burner headsfor the five sections of the radiator. The burner base 44 extendsdownwardly from the plate 41 and has a chamber.

45 communicating with all the burner heads 43. The mixing tube 46 iselbow-shaped and is screwed upwardly into the bottom of the base 44preferably at its longitudinal center. The gas cock 47 carrying a gasnozzle is screwed into the end of the mixing tube 46, and the gas pipe4S leads to the gas cock. `ijerforations 49 are formed through the plate41 along the sides of the base 44 to supply air to the combustionchamber 17 around the burner heads 43. The chamber 50 extends the entirelength of the radiator on the back side under the top 12 and between thebaffle 16 and the rear wall 9, and the by-pass 15 leads downwardly fromthe center of this chamber.

In the practical operation, a lighted match or taper is inserted throughone of the lightin g openings 1S, the gas cock 47 manipulated to turn onthe gas, and the gas burns from the burner heads 43 in the combustionchamber 17, and immediately the rush of hot air upwardly will start theinjector, consisting of the pipe :27 and the elbow 2S, to start thedraft up theV stove pipe leading from the stove pipe nipple 26.Continued operation will cause the hot products of combustion to passupwardly through the iiues 19 to the return bends 35 and downwardlythrough the flues 2O to the ends of the chamber 50 between the baffle 16and the rear wall 9, then upwardly from the center of the chamber 50 tothe iue Q1 and outwardly through the pipe nipple 26 and up the stovepipe or chimney. rThis tortuous circulation will heat a large amount ofradiating surface and at the same time requires a steady draft from thestove pipe or chimney, and when the draft is unsteady, and especiallywhen there is a back-draft, there has heretofore been a liability ofextinguishing the flames from the burners and I have found by muchexperimenting that by providing the by-pass opening lleading downwardlyfrom the chamber 50 to the bottom of the combustion chamber I avoid theliability of putting out the fire. A sudden gust of wind blowing the vproducts of combustion backwardly down the Vflue will cause compressionin the flue 21, forcing the draft downwardly through theby-pass 15,thereby stimulating the circulation within the radiator instead ofretarding it. This communicating chamber 50 collecting the products ofcombustion from the flues together with the by-pass opening 15 is ofygreat importance.

Various changes may be made in the details of construction withoutdeparting from the spirit of my invention as claimed.

I claim:

1. A radiator comprising a supporting sec tion, intermediate fluesections upon the supporting section, anda cap section upon the fluesections; thus forming a combustion chamber, a connecting chamber, iiuepassages leading upwardly from the combustion chamber and down to theconnecting chamber, a flue leading upwardly from the connecting chamber,and a bypass leading downwardly'from the Vflue to near the bottomofthecombustion chamber. Y

2. vA radiator comprising a supporting secA tion, intermediate linesections upon the supporting section, and a cap section upon the fluesections; thus forming a combustion chamber, a connecting chamber, fluepassages leading up from the combustion chamber and down to theconnecting chamber, a blind flue leading upwardly from the center of theconnecting chamber, an outlet below the-upper end of the blind liuc, anda bypassleading downwardly from the bottom of the flue to near thebottom of the combustion chamber.

3. In a radiator, means forming a combustion chamber and -a connectingchamber, means forming line passages Leading .up from the combustionchamber and down to the connecting chamber, and a flue leadingupwardlyfrom the center of the connecting chamber; there being a bypassleading downwardly from the bottom -of the flue to near the bottom ofthe combustion chamber.

In testimony whereof I have signed my name to this specification.
